Dixon's Portable Electric Hydrostatic Test Pump (ETP)

Features:

• 110 volt Portable Hydrostatic Electric Pump - Model (ETP)

• 3000 PSI maximum test pressure

• 1.3GPMfillrate(at60PSIinletwaterpressure)

• Quick connect garden hose coupler for water supply line available

• ½" x 25' intermediate hose with brass Straight-Thru Quick Coupler x NPSM swivel connection

• ½" brass Straight-Thru plug on pressure outlet

• 0–3000PSIbackmountliquidfilledpressuregauge

• Test caps, test plugs and pressure relief valves available. Consult the current Dixon Price List (DPL) for part numbers and pricing.

Recommendations

• If an extension cord is needed, the following wire sizes must be used: 25' cord - not less than 14GA wire 50' cord - not less than 12GA wire 100' cord - not less than 10GA wire

Electric damage or personal injury can result from using improperly grounded outlets. Only a properly grounded 115 Volt outlet accepting three pronged plug should be used.

Serious damage can result from improper or inadequate electric set up. Fuses, wiring and electrical codes for proper amperage and grounding should be checked.

Make sure that no water / liquid is anywhere that could cause electric shock to the operator (e.g.onthefloororpumpwhereitcouldcomeincontactwithelectricconnection).

Safety Precautions

• Electric 1. Pump is designed for the testing of rubber hose. We do not recommend it for any other application.

2. Adequate steps should be taken to protect property and personnel in the event of a failure during a test. These steps should include, but are not limited to the following:

a) Only trained personnel should conduct hydrostatic testing. b) Use of safety glasses or shields for personnel conducting test and witnessing

test. c) All personnel should be perpendicular to the test sample and at least 15' away. d) Place test sample in a protective enclosure. e) Restrain both ends of the test sample to prevent hose from whipping in case of a

failure. f) If testing is done outside of a protective enclosure, restrict the movement of the

couplings by the use of sandbags or other means. g) Useonlywaterasatestfluid.

3. Allincidentalfittings,intermediatehoseandpipingshouldberatedat3000PSIminimum.

4. Before removing or adjusting any part of the pumping system or test sample the following precautions should be exercised:

a) Shut off pump. b) Shut off water supply. c) Release pressure inside the test specimen (hose) through bleed valve.

Procedure for Hydrostatic Testing using Electric Test Pump (ETP)

It is very important to know the parameters of the test being conducted. Follow the recommendations of the hose manufacturer, the Association for Rubber Products Manufacturer's (ARPM) ,OSHA,orotherregulatorybodiesguidelinesforspecifictestparameters.Thetestshould be carefully monitored and all results recorded. Dixon recommends the following sequence for a successful test:

1. Determine the test pressure of the assembly to be tested.

2. Make sure that the test caps or test plugs and all connections are tight on the test sample.

3. Connect test specimen (hose) to high pressure outlet intermediate hose. Connection between test specimen (hose) and intermediate hose should be tight.

4. Connect the bleed-off valve to the other end of the test sample.

5. Open the bleed-off valve on the test sample.

6. Openwaterinletvalve(1-seedrawingonpage6)tofilltestspecimen(hose)

7. Fill test sample with water. Vent all air from test sample by keeping the bleed-off valve elevated until a solid stream of water (no bubbles) is coming out of the bleed-off valve.

8. Close the bleed-off valve at this point. Recommended bleed-off valve 3,000 PSI minimum.

9. Turn pressure control knob (2 -see drawing on page 6). Pressure knob located at left hand side of pump.

10. Start pump (3 - see drawing on page 6). Switch is located on the same side of the pump as the pressue control knob.

Warning!

Do not turn off water supply once test sample has been filled with water

11. Turn pressure control knob (2 - see drawing on page 6) clockwise until desired test pressure is shownonliquidfilledpressuregauge(5-seedrawingonpage6).

12. Hold test pressure until test duration requirement is met.

13. Turn pressure control knob (2 - see drawing on page 6) off (counter clockwise).

14. Turn off pump (3 - see drawing on page 6). This unit has a manual pressure relief knob (black knob - 4 - see drawing on page 6) To release pressure turn this knob from 3 O'clock position to the 6 O'clock position. To generate pressure the switch must be in the 3 O'clock position (see figure1onpage6).

16. Turn off water inlet valve (1 - see drawing on page 6).

17. Open bleed-off valve to release remaining pressure inside test specimen (hose).

18. Disconnect test sample from intermediate hose.

19. Drain water from test sample.

\WARNING

When relieving the pressure and draining the test sample, many gallons of water may be released on the floor or ground. Use all precautions necessary to ensure that no one slips

or falls as a result of this water being on the floor or ground.
